In the specific technical scheme of the invention, a seed suction disc 4 is arranged between the seed sowing shell 1 and the air suction shell 2, and a seed suction hole 20 is arranged on the seed suction disc 4. The seed sowing device also comprises a seed sowing shaft 5, a seed changing shaft 6 and a flange 3; the seed sowing shaft 5 sequentially penetrates through the air suction shell 2, the flange 3, the seed suction disc 4 and the seed sowing shell 1, drives the flange 3 and the seed suction disc 4 to synchronously rotate and is driven by a motor, so that the processes of seed suction and seed sowing are finished.
In the specific technical scheme of the invention, the seed suction disc 4 is arranged on the flange 3, the flange 3 is arranged between the seed sowing shell 1 and the air suction shell 2, a seed box 9 is arranged at the seed box inlet and moves along with the rotation of the seed box disc 8, and the automatic opening and closing during the small-seeding quantity seeding and installation can be realized due to the action of the groove slide way 10. The shaft changing shaft 6 is controlled and connected by a motor, the shaft changing shaft 6 drives the seed box disc 8 to rotate, and a baffle 21 is arranged inside the seed sowing shell 1.
When the seed sowing device is used specifically, seeds are stored in the seed boxes 9, the seed boxes 9 are installed on the seed box tray 8, when the seed sowing device works, the motor drives the seed changing shaft 6 to rotate, the seed boxes 9 where the seeds to be sown are located are moved to the seed inlet 11, the seed box door 7 is opened under the combined action of the groove slide ways 10 and the protrusions 17, the seeds enter the seed sowing shell 1 from the seed inlet 11, all the seeds enter the seed filling chamber 12 under the blocking of the baffle plate 21 and are gathered in the seed filling chamber 12, then the motor drives the seed sowing shaft 5 to rotate, the seed sowing shaft 5 penetrates through the flange 3 and is fixed with the flange 3 to drive the flange 3 to rotate, the seed suction disc 4 installed on the flange 3 is driven to rotate, the seed suction holes 20 are formed in the seed suction disc 4, the seeds are adsorbed to the seed suction holes 20 under the action of negative pressure and rotate along with the rotation of the seed suction disc 4, due to the action of the air suction cavities 14, the negative pressure can be applied to the seeds all the way to the position above the seed feeding port, and when the seeds are rotated to the position above the seed feeding port 15 through the conveying cavity body 13, the seeds are blown off due to the positive pressure and fall into the field from the seed feeding port.
The technical solution of the present invention is further explained as follows:
the groove slide way 10 is arranged in the seeding shell 1, the seed box door 7 is provided with a protrusion 17 which can move in the groove slide way 10, the top end of the groove slide way 10 is convex, when the seed box 9 moves to the upper part of the seeding shell 1, namely the convex position of the groove slide way 10, the seed box door 7 is controlled to be automatically opened through the groove slide way 10, and the seeds in the seed box 9 can slide into the seed filling chamber 12, so that the seeds can be filled; the seed box disc 8 is arranged on the outer side of the seed sowing shell 1, the seed changing shaft 6 can be controlled by a motor to rotate, and the seed changing shaft 6 drives the seed box disc 8 to rotate. The groove slideway 10 and the seed box tray 8 can realize the automatic seed changing function.
The seed discharging plate 16 is arranged at the lower part of the seed discharging shell 1 and can be controlled by a motor to discharge all seeds. Can realize the automatic seeding function. The seed box disk 8 and the seed discharging plate 16 are driven by a motor, and automatic seed changing and discharging can be realized. When the seeds enter the seed filling chamber 12 from the seed inlet 11, the baffle plate 21 is arranged inside the seed discharging shell 1 to baffle all the seeds into the seed filling chamber. When the seed box is in work, the motor drives the seed changing shaft 6 to rotate, the seed changing shaft 6 drives the seed box disc 8 to rotate, so that a seed box 9 needing seeding moves to the top end of the seeding unit, and due to the convex effect of the top end of the groove slide way 10, the seed box door 7 is opened, and seeds enter the seed filling chamber 12 from the seed inlet 11.
When the seed sowing device works, the seed suction disc 4 rotates along with the seed sowing shaft 5, seeds are adsorbed on the seed suction hole 20 under the action of negative pressure of the air suction cavity 14 and rotate along with the seed suction disc 4, so that mixed seeds cannot be generated, when the seed suction disc rotates to the tail end of the conveying cavity 13 and is right above the seed throwing port 15, the seeds are blown off under the action of positive pressure, and the seeds do free falling motion and fall into a field.
After the seed box 9 finishes seeding, the seed discharging plate 16 is opened, and all the seeds in the seed filling chamber 12 are discharged out of the machine, so that seed cleaning is finished. Doing so cyclically. The invention utilizes the advantages of the air-suction type seed sowing device to adsorb seeds with high precision, and utilizes the structures of the groove slideway 10, the seed box 9, the seed box disk 8 and the like to realize rapid seed changing and meet the requirements of cell breeding and sowing.
In the seed sowing device, the seed sowing shell 1 and the air suction shell 2 are connected by bolts, and the two shells are mutually matched and connected and fastened by bolts. The seeding shell 1 has the function that seeds fall into the seeding shell 1, seeding is carried out in the seeding shell 1 under the action of the seed suction disc 4, and the seeds are discharged out of the seeding shell 1; seed metering casing 1 one side still is equipped with recess slide 10, recess slide 10 top sets up to protruding type structure, and the effect of recess slide 10 is the switching of control seed case door 7, specifically does, seed case door 7 lower extreme is equipped with arch 17, protruding 17 place in recess slide 10, and can slide in recess slide 10, when protruding 17 of seed case door 7 lower extreme slides the protruding type structure in top of sunken slide 10, because recess slide 10 with the distance of seed inlet 11 is greater than the length of seed case door 7, consequently seed case door 7 is in the open mode for the seed falls into seed inlet 11, and the seed then gets into seed metering casing 1 through seed inlet in, and during other positions of recess slide 10, seed case door 7 is the closed mode.
The outside of air suction shell 2 has two gas pockets, one connects the positive pressure pipe, and one connects the negative pressure pipe, and because the effect of negative pressure during operation, the seed is adsorbed on seed suction dish 4, follows seed suction dish 4 and moves, when moving to the position of positive pressure hole place, because the effect of malleation, the seed is blown off, and free fall discharges outside the seed metering ware.
The seed suction disc 4 is sleeved on the flange 3, and the seed suction disc and the flange are arranged between the seed sowing shell 1 and the air suction shell 2 and are used for sucking seeds and driving the seeds to move. The seed shaft 5 passes through the air suction shell 2, the flange 3, the seed suction disc 4 and the seed discharging shell 1, and rotates to drive the seed box disc 8 and the seed suction disc 4 to rotate; the seed changing shaft 6 penetrates through the seed sowing shell 1, the flange 3 and the seed box disc 8, and the seed box disc 8 is driven to rotate by the rotation of the seed changing shaft to complete the process of the seed box disc 8; the seed shaft 5 and the seed changing shaft 6 cannot rotate simultaneously and are fixed by a bearing, so that the seed box disc 8 and the seed discharging shell 1 are connected together by the seed changing shaft 6, but the two shells cannot move simultaneously, so that a little gap is formed between the two parts to rotate the seed box disc 8. 8 seed inlets are arranged on the outer side of the seed box tray 8, so that seed boxes can be directly inserted, and the seed boxes can be directly pulled out after being used up, thereby being convenient for seed changing.
Various other changes and modifications to the above-described embodiments and concepts will become apparent to those skilled in the art from the above description, and all such changes and modifications are intended to be included within the scope of the present invention as defined in the appended claims.
